MAINTENANCE

CLEANING THE BACKPACK SPRAYER:

Press the trigger on the sprayer handle to release the pressure remaining through the lance.

Unscrew tank cap, if the outside of the cap is dirty, thoroughly clean the area around the thread

and thread O-ring.

Clean the inlet filter and tank cap in clean water.

Empty the tank and fill with clean water (with detergent added to the water if necessary).

Spray the water out of the backpack sprayer until the tank is empty (This cleans the nozzle and

valves).

Leave the backpack sprayer open and allow it to dry.

CLEANING THE FILTER IN THE SPRAYER HANDLE:

Unscrew the union nut and pull the hose with filter out of the sprayer handle.

Rinse the filter under running water and reattach the sprayer handle.

CLEANING THE PUMP:

lf the pump does not provide pressure after cleaning your backpack sprayer you must also clean

the pump.

Push out the locking ring (using a screwdriver, for example) and pull the joint rod out of the pump.

Unscrew the union ring and pull out the pump.

Inspect the pump O-ring and install a new O-ring if necessary.

Pull out the inner part of the pump and the gasket.

Clean all pump parts and gaskets with water (and detergent).

Reassemble the pump in the reserve order.

NOTE: When assembling the pump ensure that the pump gaskets are seated properly after

installation and are not squashed.

At least once a year clean pump thoroughly, re-grease or lubricate all moving parts.

WARNING:

When assembling and servicing, carefully insert the pump piston without forcing, so as not to

damage the gasket.
